SPECIFICATION forming part of Letters ratentrr 726,746, dated April 28, 1903.

Application'filed January 13, 1903. Serial No. 138.890. (No model.)

T0 at whom it may concern;

Be it known that I, GUSTAF A. Pnrnnson, a citizen of the United States, residing at Sycamore, in the county of Dekalb, State of Illinois, have invented'certain new and useful Improvements in .Wind Shields for Hay- Loaders, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a wind-shield for hay-loaders, and particularly to a pivoted device at the delivery end of the loader.

The invention has for an obj ectto provide supporting means for holding the wind-shield or board in an extended. position at the upper end of a hay-loader, so as to protect the hay thereon from the action, of the wind, which would blow it from the loader, and also to provide a directing-board for discharging the hay into the proper position upon the wagon'being loaded. 1

A further object'of the invention is to provide means for retaining thisboard in a pivoted position against the under side of the loader, so that it is completely out of the way and protected from injury.

Other and further objects and advantages of theinvention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a perspective of the invention, showing the board in posi-;

tion for use upon a hay-loader; Fig. 2, a do tail perspective of one of-the braces for the board; Fig. 3, a detail end. elevation of the manner of pivoting the board, and Fig. 4 a similar view of the board'folded against the loader.

Like letters of reference refer to like parts in the several figures of-the drawings.

The letterA designates a hay-loader, which may be of any desired construction and adapted to discharge the hay at its upper end A, so as to form astack or be loaded upon a wagon located adjacent thereto. At the upthe board desired manner.

throughout its length in the most For the purpose of supporting this board in the position shown in Fig. 1 to form a wind-shield and also a guide .to the hay being loaded a'hinged support 0 is provided and is composed of two members, one of which is pivoted at C to theboard and the other upon the pin 0 to the frame of the loader, While the meeting ends of these members are pivoted together at O and provided with stop-lugs C to limit their downward direction, yet permit a free upward movement intothe position shown in Fig; 4. It will be seen thatthe joint ofthis support can be easily broken by an upward pressure to close the shield against the loader.

For the purpose of holding theboard in its folded position (shown in Fig. 4)a latch D has been provided 'at'the free end of the board and is preferably formed of spring material, having the shoulder D to engage behind the pin or suitable projection O on the frame of the loader.

Under many conditions it is found desirable to use a brace in addition to the support, and a preferred construction thereof is shown in detail in Fig. 2, where "the bar E is pivotally connected atits end E" to the free end of the boardby means of-a strap E secured to the board, While its opposite end is adapted to'pass through a slotted holder E secured to a fixed portion of the frame of the loader. The slot E in this holder is of sufi'icient size to permit the bar E to pass freely therethrough, while said bar is provided at its opposite ends with notches E upon one face and a spring E upon the opposite face, having its ends free adjacent to the slots E so as to bear against one wall of the slot E and cause the wall of the notches E to engage the opposite wall of the slot, thus providing a solid brace for the wind-shield when the same is found necessary. In order to permit the barpassing through the holder E to assome the necessary inclination incidentto thefolding of the shielflpthis holder is pivbreakage of the parts in the folding of the shield.

In the operation of the invention the Windshield is lifted into the position shown in Fig. 1 and there supported, so as to protect the upper end of the loader above the wagonbody from the action of the wind, which frequently blows the hay from the inclined surface of the loader, thus causing a very serious objection to the operation thereof and failing to raise the desired amount of hay for loading the wagon. At the beginning of the loading this shield also keeps the hay from falling between the hay-loader and the ground, and when closed the shield prevents the hay from being drawn back by the carrier-slats of the loader. The shield also enables the operator in loading the wagon to build up the load square at the rear thereof as well as at the front, as when the hay reaches the shield it can be folded against the loader and the loading operation continued. It will be seen that the construction of hinged support permits the ready opening into position of the shield, while the brace also facilitates this operation as soon as the spring-latch is released from the loader and when the weight of the shield renders necessary, this brace relieves the support of the strain caused by the hay falling upon the shield.

It will be obvious that the invention can be applied to any character of hay-loader and that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-

1. A wind-shield for hay-loaders comprising a shield pivoted at the upper portion of the loader, a support therefor composed of independent members pivoted together at their meeting ends and pivoted to the shield and loader at their opposite ends,and a springlatch carried by the free end of the shield and adapted to engage a portion of the loader when the shield is folded; substantially as specified.

2. A wind-shield forhay-loaders comprising a shield pivoted at the upper portion of the loader, a support therefor composed of independent members pivoted together at their meeting ends and pivoted to the shield and loader at their opposite ends, a springlatch carried by the free end of the shield and adapted to engage a portion of the loader when the shield is folded, a brace pivoted to the free end of the shield and comprising a bar adapted to pass through an apertured holder and to be connected therewith; substantially as specified.

3. In a windshield for hay-loaders, ashield pivoted at the upper end of the loader, a pivoting-strap at the free end of the shield, a bar pivoted to said strap and notched upon its under face at opposite ends,a leaf-spring upon the upper face ofsaid bar having a free end above the notch therein, and an apertured holder to engage said notches carried by a fixed portion of the loader through which said bar and the free end of the spring passes; substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
